About incron

From Debian's package description

incron is an "inotify cron" system. It works like the regular cron but is driven by filesystem events instead of time events. This package provides two programs, a daemon called "incrond" (analogous to crond) and a table manipulator "incrontab" (like "crontab").
incron uses the Linux Kernel inotify syscalls.
like cron, each user can edit its own incron tables.
incron can be used to :
notifying programs (e.g. server daemons) about changes in configuration
guarding changes in critical files (with their eventual recovery)
file usage monitoring, statistics
automatic on-crash cleanup
automatic on-change backup or versioning
new mail notification (for maildir)
server upload notification
installation management (outside packaging systems)
... and many others
